This is the chemical reaction in which chemical energy is converted to light energy. It is estimated that 90% of deep-sea animals produce some sort of bioluminescence. Considering that a large proportion of the visible light spectrum is absorbed before reaching the deep sea, most of the emitted light from the sea-animals is blue and green.
Ascidiacea, commonly known as the ascidians or sea squirts, is a paraphyletic class in the subphylum Tunicata of sac-like marine invertebrate filter feeders.

Velella. Velella is a monospecific genus of hydrozoa in the Porpitidae family. Its only known species is Velella velella, [ 2] a cosmopolitan (widely distributed) free-floating hydrozoan that lives on the surface of the open ocean. It is commonly known by the names sea raft, by-the-wind sailor, purple sail, little sail, or simply Velella.
Channichthyidae. The crocodile icefish or white-blooded fish comprise a family ( Channichthyidae) of notothenioid fish found in the Southern Ocean around Antarctica. They are the only known vertebrates to lack hemoglobin in their blood as adults. [ 2] Icefish populations are known to reside in the Atlantic and Indian sectors of the Southern ...
